Reverse Osmosis

Bulk Reef Supply takes great pride in our well-built, leak-free, affordable reverse osmosis and deionization systems. We use American made filters from Dow, Matrikx, Purtrex and American-made Mur-lok dual EPMD O-Ring fittings to construct all our RO systems. We build and sell over a variety of different RO/DI system set ups in our Minnesota warehouse so you are sure to find the right system for your space and needs. We have units for just drinking water, value systems and universal systems.

The purpose of the reverse osmosis water filter systems is to produce water safe for the aquarium by removing chlorine, nitrates, phosphates and other contaminants from your home’s tap water. It is important to install reef aquarium filters that are capable of producing zero total dissolved solids (TDS) water to ensure the health of its inhabitants and prevent algae growth. Our deionization and reverse osmosis systems provide the best reef aquarium filtration available.

Our customer service representatives are certified water specialists from the Water Quality Association.
